Snapshot AWS error

I just installed and activated Snapshot on a site but I am getting:

Warning: php_uname() has been disabled for security reasons in D:\inetpub\vhosts\domainname.com\httpdocs\wp-content\plugins\snapshot\lib\destinations\aws\AWSSDKforPHP\sdk.class.php on line 120

Is there anything I can do about this so I can use Snapshot?
